フレーム４の鋳造時に形成できて安価にできる。The rigid engine case 1 and cylinder head 3 become part of the frame, and the upper vibe and lower pipe of the frame can be omitted, making it possible to significantly reduce weight and cost. In addition, the accuracy of the connecting part is also the knock bottle 7 and bolt 11.
It can be kept high by fitting the thick part 12 of. Normally, frames made by pipe welding require correction of weld distortion, but this is not necessary. 5 and 6, air guide holes 15 in the front direction are provided in the left and right legs 6 of the front frame 4, and hoses 16, 18 are connected to the front and rear to direct the running wind. The intake air can be guided to the cleaner 19, reducing intake of hot air near the engine and lowering the intake air temperature. The air guide holes 15 can be formed at the time of casting the front frame 4, resulting in low cost.

るので安価で、スペースをとらないようにできる。As explained above, the present invention provides an engine in which a cylinder and a cylinder head are vertically provided in the upper front part of an engine case, a steering hole is provided vertically in the front end, and legs extending left, right, rear, and downward are provided. A frame is provided, the legs of the frame are fastened to the cylinder head, a rear pipe is fixed to the left and right vertical frames, a rear frame is provided, and the left and right vertical frames are fastened to the rear of the engine case. The front fork is attached to the steering hole, and the rear fork is attached to the left and right vertical frames, so the highly rigid engine forms part of the frame, the front and rear frames can be made smaller, and the front fork is attached to the left and right vertical frames. It can be made into pumice, lowering costs, can be assembled with high precision, and does not require correction like welded frames. Additionally, the front frame can be disassembled, making engine inspection and maintenance easier. In addition, by integrally molding air guide holes on the left and right sides of the front frame legs,
Fresh air can be guided to the air cleaner, reducing intake of hot air, and since the air guide hole is integrated into the front frame, it is inexpensive and saves space.
